Smart PV combiner box design should have the following characteristics,
(1) Meet the requirements for outdoor installation
(2) Can be connected simultaneously to eight photovoltaic arrays, each with 16A, 1000Vdc fuse (replaceable other grades)
(3) With a PV-specific High voltage lightning arrester, are equipped with lightning protection Positive Negative
(4) Using positive and negative seperately in series four-pole circuit breakers to improve the DC voltage value
(5) Monitoring input current array, the unit LED display and output current through the RS485
(6) Monitoring the voltage after the jointed current, the unit LED display and output voltage through the RS485
